Abstract

The invention discloses a high-wear-resistance rubber-based composite material and a preparation method thereof, and belongs to the field of polymer composite materials. The composite material provided by the invention comprises the following raw materials in parts by weight: 100 parts of rubber, 2-12 parts of an active agent, 0.5-2 parts of an anti-aging agent, 20-70 parts of carbon black, 1-20 parts of a plasticizer, 0.5-2 parts of a vulcanizing agent, 0.5-2 parts of an accelerant and 1-50 parts of aramid fiber treated by an ionic liquid ethanol solution. According to the high-wear-resistance rubber-based composite material prepared by the invention, the aramid fiber and the rubber base are treated by using the ionic liquid, so that the adhesiveness is remarkably improved, and the tear resistance and the wear resistance of the composite material are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a bonding method for high wear-resistant rubber-based composite materials. Background technique [0002] With the development of rubber industry technology, higher and higher requirements are put forward for the performance of rubber materials. Introducing high-performance fibers, such as aramid fiber, into rubber matrix to prepare composite materials has become one of the hotspots in research and application. At present, aramid / rubber composite materials are widely used in tires, conveyor belts, seals and wipers and other fields. These products all put forward higher requirements on the mechanical properties and tribological properties of materials. Better mechanical / tribological properties are of great significance to prolonging the service life of products, ensuring product safety and reducing energy consumption. However, aramid fiber / rubber composites a...
